true if newView has been restored.

Parameters¶

androidJvm


retainedRenderings	the renderings to be considered hidden after this update. Any associated view state will be retained in the cache, possibly to be restored to newView on a succeeding call to his method. Any other cached view state will be dropped.
oldViewMaybe	the view that is being removed, if any, which is expected to be showing a Named rendering. If that rendering is compatible with a member of retainedRenderings, its state will be saved.
newView	the view that is about to be displayed, which must be showing a Named rendering. If compatible view state is found in the cache, it is restored.
